TUNIS - A Tunisian diplomat and an embassy worker kidnapped earlier this year by unknown gunmen in Libya arrived at dawn on Monday at a Tunis airport after being freed on Sunday.

With Libya's government weak and its armed forces still in formation, armed groups have targeted foreign diplomats for abduction this year to pressure for the release of Libyan militants held in jails overseas.

The Tunisian diplomat who worked as an adviser to the embassy was kidnapped in Tripoli in April. The other embassy official was taken separately.
